Problem running After Effects CS3/4

I've been having trouble running After Effects CS3 in 10.6.1 now...the installation went smooth but it crashes whenever I load it as shown below.

I managed to uninstall it and install CS4 and then ran into installations problems and then it said that After Effects was successfully installed. When I load up After Effects on that, it gives me some Language error with en-US and all. I even uninstalled it and then at the end it said that Done with Errors and listed possible options for fixing it, which I tried but nothing happened. I even reinstalled CS4 and wound up with problems again.
